Abstract

Obsessive compulsive disorder (OCD) is a frequent, chronic, costly and disabling disorder characterised by recurrent intrusive ideas, images, ruminations, impulses and thoughts (obsessions), which increase anxiety and repetitive patterns of behaviour (compulsions), in an attempt to decrease anxiety. It is one of the most disabling psychiatric conditions, and has a negative impact on the quality of life of both patients and those close to them. When correctly recognised and diagnosed, it can be successfully treated. The World Health Organization ranks OCD as one of the 10 most disabling conditions in terms of lost income and decreased quality of life.
